Claim 1
Independent Claim
134 words
A heat pipe having an evaporator, a condenser, a heat exchange fluid and a transfer means for transferring the heat exchange fluid between the evaporator and the condenser, wherein the improvement comprises: said transfer means consists of a flexible pipe connecting the evaporator to the condenser and a flexible wick lining the inside wall of said flexible pipe and extending into said evaporator and said flexible pipe and extending into said evaporator and said condenser respectively, whereby said evaporator and said condenser may move relative to each other, and a heat exchange fluid is transferred between the evaporator and the condenser, clamp means operably connected to the outer circumference of said flexible pipe for reducing the circumference thereof to thereby restrict the transfer of vaporized heat transfer fluid from the evaporator to the condenser.
